IMPROVED DEVICE I'OR` SOLDERING GANS.

TO ALL WI-IOM IT MAY CONCERN:

Be it known that we, JOHN C. UNDERWOOD and PETER JOHNSON, of Richmond,'in the county o'f Wayne, and State of Indiana, have invented a new and useful Improvement in Manufacturing Fruit-Cans; and Awe do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, referencefbeing had to the accompanying drawings, forming part of this specification.' i

This invention relates to certainjmprovements in apparatus for holding fruit-cans while being soldered, and it consists in attaching to the shafts of the expander aseries of springs, connected by means of hinges to the bandsywhich fit again st the inner surface of the can, whereby the expander shall be accommodated to any variation in the size of the cans being soldered. And it further consists in a series of wheels for distributing rosin from the box containing the same, as will be hereinafter more fully described, and also in attaching a. spring guide to, the supporting frame, whereby the can is properly centred.

Figure 1 represents a vertical section of the machine, showing the can in place in the machine and expanded to the proper diameter. The expander is alsoshown as it appears when pressing out the sides of the can, it being through the line x :c of fig. 2.

Figure 2 is a cross-section of the machine through the line gj y of fig. 1.

Similar letters of reference indicate like parts. i

A is the body of the can, B is the head, and C is the bottom; D is the expander; D' the expander shaft;

E represents the expanding bands; F is the frame which supports the machine; Gis an adjustable pan orbasin; Gr represents basins or boxes which contain rosin, and I-I represents wheels which distribute lthe rosin. The expander is formed of a shaft, D', with eight rods, (more or less may be used,) which are attached to each end of four springs, a. These springs are attached to the shaft at their middle by screws or otherwise, and are somewhat circular inform, as represented. The bands E are attached to the springs a by hinges, and the ends of the springs are confined by clasp-pieces which are attached to the shaft. vUpon the outer end of each'pailr ofthe bands E there is attached by a jointed 4connection a pla te marked e in the drawing. In shape` this plate conforms to the circle or shape of the can. It will be seen that this expander, with theplate c, will fold down on to the four springs, assuming nearly a square form when in that position. J is a hand-wheel on the shaft D. J is a false canhead, which is attached permanently to the shaft D'. h isa centre-pin which passes through the frame F, having a disk, d, upon its inner end. Its outer end is in contact with a spring, e, whichfpresses the pin and the disk upon the end inwardly. The disk is placed loosely upon the end of the centrepin, so that 'it may readily adjust itself to the bottom ofthe can. K is a forked guide, upon which one end of the can rests when being adjusted forysoldering. L is a bent rod, which supports one side' of the basin G, as seen in fig. 2. The rod L is attached toi'the frame F. Only one end of the rod is seen in iig. 2. The basin G is attaebedto this ro'd on one side by a hinged connection, which allows the opposite side to be raised up. '.lhis movement of the basin brings the wheels H in contact with the can where the rosin is to be distributed. When thus in contact the can is revolved, so that the wheels H traverse the whole circumference ofthe can. There are partitions, c, in the pan or basin G, upon which the shaft m (to which the wheels are attached) rests. These wheels are formed by compressing elastic or fibrous material between two disks. They revolve iu the rosin which is contained in the compartments G G of the basin. o

e In operating the machine, the parts of the can are put together, (can shape,) and the expander is inserted,

when a slight but quick rotary movement throws out the bands E, with the plates c, as seen in the drawing, thereby expanding'the body of the can to the required diameter. It will be understood that the body of theV can is only formed, it is not soldered;V all the soldering is done after the can is expanded. The expander is supported at one end by the disk cl and at the other-end by acentre on the frame F, as seen in the drawing.

What we claim as new, and desire to secure by Letters Patent, is

I. The springs a, in combination with the expander-shaft D', bands E, and hinges, substantially as and for the purpose specified.

2. The frame F, disk d, and adjustable spring-guideK, constructed and arranged as described for centring the can, substantially as herein set forth.

3. The combination and arrangement of the expander D, frame F, and rovsin-box G',- substantially as described for 4the purpose Specified. Y

4. Thecompartments G and wheels H, with the pan G', for distributing the rosin, constructed and arranged to operate substantially as and for the purpose set forth,v JNO. o. UNDERWOOD,

PETER' JOHNSON.
